Abstract:

BACKGROUND: Currently, interbody fusion implants in lumbar pedicle screw fixation surgery under endoscopy include natural biomaterials, synthetic materials and composite materials, which have their own advantages and disadvantages.
OBJECTIVE: To explore how to choose the most suitable implants by analyzing and discussing the characteristics of the interbody fusion implants in lumbar pedicle screw fixation surgery under endoscopy.
METHODS: We searched the Wanfang and Medline databases (1999-01/2010-12) with the keywords of “endoscopic, screw-rod fixation, interbody implant” for the articles regarding the interbody fusion implants in lumbar pedicle screw fixation surgery under endoscopy.
RESULTS AND CONCLUSION: As the size of interbody fusion implants matches the request of the endoscopic pathway, it is widely used in lumbar pedicle screw fixation surgery under endoscopy nowadays. The materials of cages have evolved from the first initial materials such as titanium alloy to biodegradable and absorbable biomaterials. The allograft cortical bone fusion materials have also emerged, which are most close to the so-called “gold standard”. Each intervertebral fusion device has its own advantages and disadvantages. The choice of the most suitable interbody fusion implants should be made according to the patient’s imaging and the characteristics of lumbar spine internal fixation.
